One of the interesting Tucanoichthys tucano facts is that it has a dark stripe on the side of its body.

The Tucanoichthys tucano is a ray-finned tetra fish found in the continent of South America.

More specifically, it is native to the upper Negro river basin range in the Amazonas state in Brazil. It is a popular and sought-after aquarium fish outside Brazil due to its beautiful appearance.

The Tucanoichthys tucano size is only around 0.6-0.7 in (15-17 mm) which would make it vulnerable to predators, but due to lower predator populations in the Tucanoichthys tucano range, the species survives and thrives.

The Tucanoichthys tucano species prefers fresh water which has been darkened by the tannins from the leaves and branches that fall in the water in the riverine habitat. The Tucanoichthys tucano life is also characterized by aggressive territorial behavior during the breeding season.

The conservation status of the Tucanoichthys tucano has not been evaluated by the IUCN and it remains a sought-after domestic aquarium fish around the world.

The upper bodies as well as the heads of tetra Tucanoichthys tucano fishes are bright gold. The bellies are white and the lower gills have a pinkish color.

The gold color sometimes may extend to the top lobe for some individual fishes, but mostly the fins are all transparent. Their most prominent feature is the dark stripe along the sides of the body.

This dark stripe begins at the gill and tapers off at the caudal peduncle. Toucan tetras display prominent sexual dimorphism. The females have rounder bodies than the males, even more so when they are carrying eggs.

The males also tend to be more brightly colored than the females. The anal, dorsal, and caudal fins of males also have a pinkish-red color.

Would they make a good pet?

Yes, Tucanoichthys tucanos make great pets. Caring for them is relatively easy, not much harder than other fish.

They should be housed in a nano or small aquarium with plenty of plant matter that imitates their natural habitat. It would be unwise to keep them with bigger fish for fear of predation.

They are a peaceful species in domestic settings but males may become aggressive with other males, but having 8-10 tucanos makes them an interesting fish to watch. They can be given a varied diet of dry as well as live food.

The ideal temperature for the fish is 68-82.4°F (20–28 °C) and a pH of 4-6.5 and hardness of 18-143 ppm should be maintained. The addition of plant matter, like dried leaves, as well as giving habitat familiarity, gives rise to microbial colonies.

The best lighting to be used for tucano fish tanks is dim. You may also add sandy substrates as well as alder cones, driftwood branches, peat, almond leaves, and roots.

Did you know...

The natural microbe colonies that exist in the natural habitat of Tucnoichthys tucanos sometimes prove to be a source of food for juvenile fry fish. The tannins released from the dead leaves are naturally beneficial to the growth and life of tucanos.
